Pro tip: stop buying pre-ground and get a $20 blade grinder, it beats the stuff in the bag every time
I brewed pre-ground from the grocery store for about 4 months because I thought a real grinder was too much hassle, then a coworker in Fresno handed me his old blade grinder and the smell alone made me feel dumb. Yeah it's uneven and the cheap ones get hot, but 15 seconds of pulsing on beans roasted two weeks ago tastes way better than anything that's been sitting on a shelf. Anyone here actually go back to pre-ground after grinding at home, or is that just me being dramatic?
